Phosphatase hydrolysis
WebNov 4, 2024 · Alkaline phosphatases are a group of isoenzymes, located on the outer layer of the cell membrane; they catalyze the hydrolysis of organic phosphate esters present in the extracellular space. Zinc and magnesium are important co-factors of this enzyme. Although alkaline phosphatases are present in dif … WebWhat is a phosphatase reaction? Phosphatases catalyze the hydrolysis of a phosphomonoester, removing a phosphate moiety from the substrate. … The net result of the reaction is the destruction of a phosphomonoester and the creation of both a phosphate ion and a molecule with a free hydroxyl group.
